Draw a n-channel (p-channel) MOSFET. Explain how it works.

How are the contacts made at the source, drain, gate, and body?

Draw the depletion regions and the electric fields.

Draw the charge density in the channel when the saturation voltage is applied.

How would you calculate the drain current?

What are short channel effects?

For which applications are MOSFETs used? Why?
